摘要： A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit; a support that supports the X-ray generating unit and the X-ray detecting unit; a drive mechanism that turns at least the X-ray generating unit and the X-ray detecting unit by driving the support; a displacement mechanism that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit; a subject holding unit that holds an imaging subject; a turning controller that controls the turning by a drive mechanism and the displacement mechanism. The turning controller controls the drive mechanism and the displacement mechanism so as to add the movement avoiding the contact with the shoulder of the imaging subject during the turning of the X-ray generating unit and the X-ray detecting unit by the drive mechanism during the panoramic X-ray imaging.

摘要： An object of the present invention is to prevent an X-ray generator and an X-ray detector that turn around a subject from contacting with the subject. An X-ray CT imaging apparatus includes a turning support that supports an X-ray generator and an X-ray detector, a turning drive mechanism including a turning mechanism and a turning axis moving mechanism, an imaging region position setting unit that receives a setting of a position of an imaging region to a local part of a dental arch of a head, and a turning controller. The position of the mechanical turning axis X1 is controlled according to the position of the imaging region set by the imaging region position setting unit.

摘要： By turning an X-ray generator and an X-ray detector around a head of a subject, an imaging region is irradiated with an X-ray beam from a plurality of directions to obtain an X-ray projection image. When a center axis X-ray of the X-ray beam passing through a turning center axis is orthogonal to a tomographic layer of interest, the X-ray detector is caused to approach the tomographic layer of interest while the X-ray generator is moved away from the tomographic layer of interest as compared to when the center axis X-ray is not orthogonal to a tomographic layer of interest.

摘要： A first position setting unit receives an operation to designate a position in a mesiodistal on a panoramic tomographic image displayed on a display, and sets a first position on a curved section based on the designation operation. The fluoroscopic imaging information providing unit provides information irradiating a subject with an X-ray beam along a direction having a component of a tangential direction at the first position of the curved section to execute fluoroscopic imaging acquiring a fluoroscopic image to a main body. A second position setting unit receives an operation to designate a position in a buccolingual direction on the fluoroscopic image displayed on the display, and sets a second position in the buccolingual direction based on the designation operation.

摘要： A dose setting unit generates dose control data in order to change a unit time dose of an X-ray beam with which a subject is irradiated during X-ray tomography. An imaging controller makes X-ray intensity when a center axis X-ray (irradiation axis) of an X-ray beam emitted from an X-ray generator is not orthogonal to a tomographic layer of interest relatively smaller than X-ray intensity when the center axis X-ray is orthogonal to the tomographic layer of interest.

摘要： A medical X-ray CT imaging apparatus includes an X-ray generator that generates a cone beam, an X-ray detector, a support that supports the X-ray generator and the X-ray detector while the X-ray generator and the X-ray detector are opposed to each other, a turning drive unit that turns the X-ray generator and the X-ray detector, which are supported by the support, an imaging information receiving unit, and an X-ray output condition setting unit. The imaging information receiving unit receives an imaging area setting relating to at least one of a size of an imaging area, an imaging purpose, and an imaging region. The X-ray output condition setting unit automatically sets an output condition of the X-ray generator according to at least one of the size of the imaging area, the imaging purpose, and the imaging region, which are received by the imaging information receiving unit.

摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a resistor for load detection; a load comparing unit; and a control unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The resistor for load detection detects a load applied to the cutting tool. The load comparing unit compares the detected load and a reference load each time driving for rotating the cutting tool in the reverse rotation direction by a predetermined rotation angle is performed. The control unit controls the driving unit based on a result of comparison by the load comparing unit.

摘要： The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); and a controller. The driving unit drives the cutting tool so as to be switchable between first driving in which the cutting tool is driven clockwise and second driving in which the cutting tool is driven counterclockwise. When a rotation direction in which the cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to the normal rotation is defined as reverse rotation, the controller sets the first driving as driving for the normal rotation when a first cutting tool rotated clockwise is held on the head unit, and sets the second driving as the driving for the normal rotation when a second cutting tool rotated counterclockwise is held on the head unit.
